In the drawing, aside rail-of an-"automobile hassis is indicated at 10. .This rail forms a supportfor the hood 11, which is shown as finished around the bottom by or wire '12. To r illO, adjacent the inner edge thereof, hi secured in any suitable: mannerfa short .pin 18, which is the lower surface of tl inclined upwardly in order to provide an upwardly and inwardly'sloping under's'ur-- face for engagement by the looking hook.

At that point in the hood chosen for the locationof the lock, the hood is reinforce d by means of a metal platelet, the lower end of which is rolled outwardlyand upwardly around the lower rolled edgeof the ho od, as shown clearly in Fig. III. The plat'ei141 scrves also as a part ofthe casing for. the v lock. Near-"the upper end of the plate there sa reamed hole formed directly opposite a hole inth'e hood 11. In the assembly ,of

the device, a bushing '15,- provided with a bevel .base to fit the reamed-hole in the plate 14, is pushed through that holexand the hole in the hood and the outer end of. the l )ush1ng,is then bentuover against the outer wall of the hood, thereby firmly at-v taching together the hood, plate and bushmg. At the .upper end'of the plate la' is an integral portioncomprising part ofthe lock casing, having a wall 16-bent outwardly at right angles from one edge of the plate 14 and a wallflz' bent at'right angles to the I wall 16, and, thus parallel to the plate14.

" The wall 17 contains a circular opening which is directly opposite to, andthe same s1zeas, the opening in the bushing 15, The

bushing 15. and the opening in the wall 17 form-bearings for a rock shaft 18, which shaft .18 protrudes through an elongatedslot' 20 in. the upper end of a flat tremity, is shaped to form a 'hook 22. The lowerend of the rod '21 also has an integral" nietal strip or bar 21 which, at its lower eX- 95 preferably terminates. flush with the outer face of the bushing '15, and is provided with j e flat side intended 'to'receive the correspondingly shaped bent out portion 23 to which is fixed the guiding clip 25, which preferably is stamped lower extremity of a coil spring24l for a purpose hereinafter-to appear. The rod 21 is capable of a sliding motion up and down,

- in which it is guided by the slot surround out of the reinforcing plate 14:. Throughout most of its length the rod 21 lies fiat against the plate 14:, being held in that position by the clip 25 and by a collar 26.

' which surroundsthe rock shaft 18.

Between the collar 26 and the wall 17 of the casing a crank 27, formed of a sheet 'metal plate folded along one edge, is mount ed upon the rock shaft 18. The latter has a flat portion 28 along one side extending from the rear .end forward as far as the hook rod 21. The holes in the collar 26 and both portions of the crank 27 are similarly shaped so as to turn with the rock shaft. The shoulder 29, formed at the end 'of the flat portion 28, byabutting against the collar 26 prevents movement of the shaft to the left as viewed in Fig. III, while its movement toward the right is prevented by a ring guard 30, which contacts with the wall 17 of the casing, the ends of the ring extending into holes in the shaft. shown at 31 in Fig. III, in order to hold it in place.

Near the outer end of the crank 27 a headed pin 32 extends through the two portions thereof, its dislocation being prevented by any suitable means, for instance, a cotter pin 33. The pin 32 forms a pivotal mounting for an arcuate shaped link 34, the upper end of which extends between the two portions of the crank 27. The lower end' of the link 34l has a perforation through which extends the upper end of the coil spring 2 1. The motion of the crank in the direction of the arrow in Fig. I- is limited by an edge of the wall 17 against which the head of pin 32 abuts.-

The operation of the device will described. is down and locked in place, and that the driver of the machine desires to open the hood, he inserts a key or operating handle in the socket 19 and turns the rock shaft 18 in the direction opposite to that of the ar row in ig. As soon as the pin has passed now be the dead center above the rock shaft. the ten-' ing a small part of the rotation of sion of the spring 24.- assists the motion durthe shaft, or until the tension of the Thereafter, further rotation of the shaft in the same direction positively lowers the link 34, and the bottom end thereof acts upon the spring 24, the coils of which arenow closed, tending to push it downwardly. This pres- It being assumed that the hood spring is relieved.

sure is conveyed by the spring to the lug 23- and thence to the hook rod 21, which accordingly slides downwardly, being guided in its motion by the sides of the slot cooperating with the rock shaft. This disengages the hook 22 from the pin 13. Now, in

order to throw the hook out from under the 27 bears against the edge of the link 34 during this latter movement, so that the linkf cannot merely swing on the pivot 32. 'From the lower end of the hnk this swinging motion is transmitted to .the spring 24, which in turn swings the hook 21 and the motion is continued until the rod is stopped by the end wall 16 of the casing as shown in Fig. II. If two or more locks are employed, the others are operated in the same manner. and the hood may then be swungup on its hinge.

In locking the hood the reverse operation is of course followed, the first part of the rotation of the shaft having. the effect of swinging the hook 22 under the pin 13, after which further rotation lifts the hook rod 21 until the hook presses against the under Y face of the pin, and then still further rotation puts the spring 24 under tension. The greatest tension obviously occurs when the pivot 32 is directly above the shaft 18, or in dead center position. Provision is made however, for a slight further rotation until the movement is stopped by the edge of the wall 17' of the casin as shown in Fig. I. \Vith the pivot in that position the force of the spring 2% acts not only .to hold the hook 22 into engagement with the pin 13, but also, to pull downwardly upon the pivot 32, and thus keep the mechanism in the locked position. As will be observed, the

force holding the hook 22 in engagement with the pin 13 acts 'entirely through the spring 24. Hence the hook and pin remain firmly in contact at all times, even though the relative positions of the hood and hood support change, as they will do more, or lesswhen the car is in motion. For this reason there is no rattling of the look.

I am aware that the particular embodiment of my invention above described, and illustrated in the accompanying drawing, is susceptible of considerable variation with out departing from the spirit thereof, and therefore I desire to claim my invention broadly. as well as specifically, as indicated by the appended claims.
